HENRY 1. SMITH, OF PITTSBUBG, KANSAS.

. DISH-WASHING MACHINE.

To all whom it may concern: 7

Be it known that I, HENRY F. SMITH, a

citizen of the United States, residing at machines and has for its primary object to receptacle or ignates a vessel provide a simple, eflicient and inexpensive device of this character whereby the dishes may be quickly and thoroughly washed or cleansed.

A further object of the invention resides in the provision of improved means for forcibly discharging the water against the dishes which are contained within a suitable receptacle.

'Another object of the invention is to provide a dish container rotatably mounted within a water vessel, said container having foraminated walls and dish supporting means upon its bottom, spiral water directing tubes arranged upon the annular wall of the container, and means arranged upon ,the exterior of said container to direct the water into said tubes when the container is rotated in either direction.

With the above and other objects in view, the invention consists of the novel features of construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of a dish washing machine embodying my improvements; Fig. 2 is a. sect-ion taken on the line 22 of Fig. 1; taken on the line is a detail fragmentary container.

' Referring in detail to the drawing 5 desreferably cylindrical in d with a plurality of supporting legs 6. This vessel may also be provided at its upper edge and on opposite sides with a handle 7. A bearing 8 is centrally arranged within said vessel and rigidly secured to the bottom thereof. Within this outer vessel the dish container or receptacle 9 is arranged, the side and bottom walls of said'container being provided with a plu 33 of Fig. 1; and Fig. at elevation of the dish form and provide Specification of Letters Patent. 7 Application filed December 6, 1911. 7 Serial No. 664,254.

Fig. 3' is a detail section Patented Mar. 19, 191-2.

rality of perforations 10 to admit .water to the interior thereof. A spider 11 is removably secured upon the upper edge of this container, the arms thereof being angularly disposed and provided with threads as indicated at 12. These threaded extremi-- ties of the spider arms are adapted to be disposed through openings in secured to the annular wall of the receptacle 9 and nuts 14 are threaded thereon to rigidly secure the spider in position. This spider is further provided with a central rectangw lar opening l5 to receive the squared portion 17 of a rod or shaft 16. The lower end of this rod or shaft extends through a central opening in the bottom of the receptacle 9 and is seated in a bearing recess provided in the block 8, said bearing block also serving to space the bottom of the dish receptacle from the bottom of the outer vessel 5. To the upper end of the shaft 16 a crank handle 18 is attached whereby the receptacle 9 may be rotated.

Within the dish bottom thereof a plurality of annular bands or rings 19 are arranged and rigidly secured. These bands or rings are arranged in pairs and the dishes are supported in a vertical position within the receptacle by placing the edges thereof between the spaced bands of each pair. In this manner a large number of dishes may be arranged within the vesseland their surfaces spaced 'or separated so that the water may contact with receptacle and upon the the lugs 13 I all portions thereof. Upon the inner face of the annular wall of the receptacle 9 a plurality of semicircular tubes 20 are spirally arranged. The upper ends of these tubes are open to discharge the water down-- wardly, and the lower ends thereof are enila'rged and disposed over the openings 21 in the annular wall of the receptacle, said tubes being rigidly secured to the inner face of said wall. The tubes 20 are also provided with a longitudinal series of openings 22 through which the water is discharged in jets as the receptacle is rotated.

In order to cause the water to enter the lower ends of the tubes with suilicient force. to move upwardly therein and be discharged from the upper ends of the tubes, I provide directing means arranged upon the exterior of the annular wall of said receptacle. This directing means consists of a hood 23 which cated at 23 the same-over the. dishes.

is provided wit-h a flange 24 rigidly secured in any desired manner to the outer face of the wall of the receptacle. The body plate of the hood is outwardly and downwardly inclined and the ends 25- thereof are loosely mounted upon the wires or rods 26 which are rigidly fixed in the ends of the body plate and the wall of the receptacle 9. Pins 27 are secured in the hood plate and extend inwardly, said pins being located adjacent to each end of said plate. construct-ion, the water is caused to enter the lower ends of the directing tubes 20 under considerable pressure.

As shown in Fig. 4, when the receptacle is being rotated in the*direction indicated by the arrow, the plate '25 forming one end of the'hood 'is moved inwardly by the pressure of water thereagainst and rests uponone of the ins 27 in an inclined position as shown in otted lines in said figure. The water entering the end of the hood over this inclined plate, is directed upwardly into the lower end of the tube 20 as the receptacle is rapidly rotated within the vessel 5. When the direction of rotation is reversed, the plate 25 will return to its normal position while theother of said plates in the opposite end of the hood will move downwardly upon the supporting pin 27. The ends of the inclined hood plate 23 are inwardly flanged as indito limit the outward movement of the plates 25. The plate 25 being inclined when in its closed position will also serve to increase the volume of water entering-the tube 20. As this water moves upwardly through the tubes, it is discharged through the openings 22 between and against the plates arranged within said vessel: The larger part of this water is, however, discharged from the upper ends of said tubesand in the rotation of the receptacle sprays In this manner it will be seen that the water is forcibly discharged in volume against the dishes so that all parts thereof are quickly and thoroughly cleaned. vThe upper end of the receptacle or container 9 is preferably provided with a bail '28 so that the same may be readily removed from the outer vessel 5 when the washing of the dishes is completed. The waterwill drain from the dishes through the openings in the bottom of the receptacle and the hot air which is held between the spaced pairs of supporting plates or hands 19 will quickly dry the dishes as it rises through the interior of the container. '1

From the foregoing it is thought that the construction and manner of operation of my improved dish washing machine will be fully understood.

The device is comparatively simple in construction and provides means whereby dishes may be quickly washed in large quantities.

By means of this I As the device is entirely constructed of sheet metal, it will further be obvious that the same can be manufactured at small cost.

that the invention is susceptible of a great many minor modifications without depart= ing from the essential feature or sacrificing any of the" advantages thereof.

Having thus described the invention whatis claimed is 1. In a dish washing machine, a water containing vessel, a receptacle for the dishes rotatably mounted in said vessel, the annular wall of said receptacle having a plurality of openings adjacent to its lower edge, tubes spirally arranged upon the inner face of said wall. and having their lower ends disposed over said openings, the upper ends of said tubes being open to discharge water upon the contents of the receptacle,- and means movably mounted upon the outer face of said annular wall and moved by the pressure of water thereagainst to forcibly direct the water into the lower ends of said tubes.

2. In a dish washing machine, a water containing vessel, a. receptacle to receive the dishes rotatably mounted in said vessel, the

annular wall of said vessel having a lurality of openings adjacentto its lower e ge, tubes spirallyarranged upon the inner face of said annular wall and having their lower ends disposed over the opening's thereof, the upper ends of said tubes being open to discharge the water upon the contents of said receptacle, means arranged upon the outer face 'of said annular wall over each of the openings therein toforcibly direct the water into the lower ends of said tubes, said means consisting of an outwardly and downwardly inclined plate, mounted between the ends of said inclined plate and the wall of the receptacle and movable by the pressure of water against the same to direct the water into the lower ends of said tubes when the receptacle is rotated in either direction.

3. In a dish washing containing vessel, a receptacle rotatably mounted within said vessel to receive the dishes, means secured upon the base of said receptaclev to support the dishes in an upright position and in separated relation, the annular wall of said receptacle being provided with. openings adjacent its lower end, tubes arranged upon the inner face of said their lower ends annular wall and havin disposedover the face of said openings, the upper ends of said tubes being open to discharge water upon the contents of the recepta cle, said tubes each being further provided w1th a longitudinal series of openings to discharge the water in jets between the dishes,

. and means arranged upon the outer face of and movable directing plates machine, a water the annular wall bly direct the water said tubes, said mean wardly adjacent each 0 and downwardly inclined plate, wardly projectin pins secured to said p its of said receptacle to forciinto the lower ends of s consisting of an outin-. late ends, and directin plates pivotally mounted between the on s of said inclined plate ceptacle and adapted inclined position by and the wall of the reto be supported in an said pins w hereby thewater is forcibly directed into the lower ends of said tubes in the rotation of the rece tacle in either direction.
